“…The dominant growth mechanism of Al 2 O 3 TGO on the MCrAlY bond coat can be regarded as the diffusion of oxygen from the outside surface of the TGO, into the interface between the TGO and the alloy matrix of the bond coat [37,60,61,[65][66][67][68]. For the bi-layered TGO found on the bond coat surface of the samples that underwent long isothermal oxidation times, the oxygen diffusion to the inside went through the mixed oxides and the α-Al 2 O 3 scale.…”

“…There have been many attempts to numerically investigate stress development in TBC systems [9,[12][13][14][15][16][17][18][19][20][21][22][23][24]. In most cases a 2D-unit cell representing a single asperity was used.…”

“…La description mécanique du phénomène d'évolution de rugosité (ratcheting ou rumpling) à l'origine de ce mode de dégradation a été abordée par plusieurs groupes, notamment par Balint et al [26] au moyen d'une approche semi-analytique et d'autres auteurs [27][28][29] au moyen de calculs par éléments finis. Une difficulté reste l'introduction dans ces calculs de lois de comportement pertinentes, notamment pour la couche de liaison.…”
